. Be it known that I, THoMAs E. HENDER- SON, a .citizen' of the United States of America, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in'Cold Processes of Repairing Radiators of Internal-Combustion Engines, of which the following is a specification.

My invention relates to a process of repairing breaks in radiator pipes in internal combustion engine equipment; and the object is to provide a process of repairing the breaks in radiator pipes, usually caused by freezing, by which process the breaks can be quickly and efliciently repaired at very small cost; and one advantage is that the process is a cold process so that no time is lostin heating and preparing for heating and the process is simple and inexpensive. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims. 7

Reference is bad to the accompanying drawings for illustration of the process;

Figure 1 is a diagrammatic view, showing some broken radiator pipes and apparatus for depositing the repairing material. Fig. 2 shows one form of a discharge pipe or Similar characters of reference are used to indicate the same parts throughout the several views.

The repairing material includes two kinds of powdered metal and a binder liquid for making a composition of semi-liquid. consistency. This composition is prepared in very small quantities,-one-half ounce being usually sufficient, and there might be use for less than a half ounce. If more is prepared than for immediate use it will be lost be-' cause it would become set or solid and useless and cannot be revived.

If the radiator has much dirt or grease accumulated thereon it will have to be cleaned before repairing. This may be done by placing the radiator in a vat of boiling water and keeping the water boiling until the radiator is cleaned. The radiator may be cleansed with acids, but the acid should be cleansed with water before repairing with the composition. The breaks in. the pipes are detected in the pipes by water tests, that is, by immersing the radiator in Specification of Letters Patent. Patented May 18, 1 920. Application filed November 22, 1919. Serial No. 339,859.

Water after closing all-the connection open-- ings except one for admission of air, and

then forcing air into the radiator -while breaks.

The composition is prepared by taking'the required quantities of the two powders and mixing with the binding liquid until the composition is of semi-liquid consistency. A'

small jar 1, adapted to contain about one- 'half'.ounce,.1s provided and the composition placed therein by removing the screw cap 2.

A depositing or discharge nozzle 3 is car ried by the top 2. The material or composition is forced out of the jar in a continuous stream through the nozzle by compressed air. This may be done by a pipe connection t which is also carried by the screw cap 2. A hand rubber bulb 5 of-rubber of ordinary type which is provided with an intake check valve 6 may be used to compress air on the composition to force the same through the nozzle 3.. For depositing the composition on'the back side of'a pipe, a nozzle 7 provided with a curved tip 8 may be used. Sufficient air may be compressed by hand for forcing the composition through the nozzle in a continuous stream until the required amount is deposited on the break to be repaired. The material or composition is spread on the broken part to suiiicient depth nections, or the connection of the core of the radiator with the upper or lower pans, but is highly successful in'repairing the breaks in the radiator pipes, as shown by actual service in repairing a number of radi- Enough lacquer is used to make a composition that is easily forced through the depositing devices.

hat I claim, is,-

1. A cold process of repairing motor radiators consisting of mixing two kinds of powdered metal and a binder liquid, projecting the mixture on the parts to be repaired, and allowing the object to remain stationary until the mixture is set or dried.

2. A cold process of repairing motor raditors consisting of mixing two kinds of powdered metal and a binder liquid in a small receptacle provided with a depositing nozzle, projecting the mixture by compressed air on the parts to be repaired, and causing the parts to remain stationary until the mixture has become dry or set.

3. A cold process of repairing motor radiators consisting of mixing two kinds of powdered metal and a binder 1i uid in a small receptacle provided with a epositing nozzle, projecting the required amount of the mixture by compressed air through said nozzle in a continuous stream on the parts to be repaired, and causing the parts to remain stationary until dr or set.

In testimony whereof set my hand, this 8th day of Januar 1919.
